Endocrinology Pharmacology Flashcards
What does Thyroid Peroxidase (TPO) and Thymosin do?
Help T-cells mature
What does vasoactive intestinal peptide (VIP) do?
Inhibits secretin, motilin, and CCK, and opens Sphincters
How does a VIPoma present?
Watery diarrhea
How does a Somatostatinoma present?
Constipation
What are the hormones with disulfide bonds?
“PIIG”: Prolactin, Insulin, Inhibin, GH (growth hormone)
Which hormones have the same Alpha Subunits?
LH, FSH, TSH, and B-HCG
What hormones produce Acidophilus?
“GAP”: GH, Acidophilus, and Prolactin
What hormones produce Basophila?
“B FLAT”: Basophils, FSH, LH, ACTH, and TSH
What hormones are released from the posterior pituitary?
ADH (supraoptic nucleus), Oxytocin (Paraventricular nucleus) by the Neurophysins
What is seen in Hashimoto’s Thyroiditis?
Antimicrosomal antibody and Anti-TPO antibody
What is the Mechanism of Action of Insulin?
Pushes K+ into the cell,
Liver: Increases Glucose storage as Glycogen, Increases Triglyceride synthesis.
Muscle: Increases protein and glycogen synthesis.
Adipose Tissue: Improves Triglycerde storage by activating Lipoprotein Lipase, Decrease circulating Free Fatty Acids
What are the Indications for Insulin?
DM Type 1; DM Type 2; Hyperkalemia; Stress induced Hyperglycemia; Gestational Diabetes
What is the Adverse Effect of Insulin?
Hypoglycemia
What are the Short Acting Insulin drugs?
Aspart and Lispro
What is the Rapid Acting Insulin drug?
Regular Insulin
What is the Intermediate Acting Insulin drug?
NPH and Lente
What are the Long Acting Insulin drugs?
Ultralente, Glargine, and Protamine
What is the Mechanism of Action of Sulfonylureas?
Closes K+ channel in the pancreatic Beta cell membrane, Reduces K+ efflux & increases Ca (2+) influx, and cell depolarize to increase secretion of insulin
What are the indications for Sulfonylureas?
NIDDM (Type 2)
What is the Adverse Effect of Sulfonylureas?
Hypoglycemia, GI disturbances, Muscle weakness, mental confusion, Sulfur allergy
Function of what cells is necessary for the action of Sulfonylureas?
Requires some islet cell function so drugs used less in Type 1 DM
What is the first generation Sulfonylureas?
Chlorpropamide and Tolbutamide?
What is the Adverse Effect for first generation Sulfonylureas?
Disulfiram like effects
What is the second generation Sulfonylureas?
Glyburide, Glimepiride, and Glipizide
What is the MOA of Biguanides?
Decrease Gluconeogenesis, Increase Glycolysis, and Increase peripheral Glucose uptake. (Insulin sensitivity)
What are the Indications for Biguanides?
First line therapy in Type 2 DM
